PROCESS OF ENAMELING.

SPECIFICATION forming part of Letters Patent No.329,165, dated October 27, 1885.

Application filed May 18, 1885. Serial No. 165,839.

To @ZZ whom it may concern:

Be it known that I, JOHN HINLEs, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented a certain Improved Process of Enameling, of which the following is a specification.

The object of my invention is to simplify the manufacture of enameled articles having designs, decorations, figures, or letters thereon.

In carrying out my invention I proceed in thefellowing manner: The body of the enamel, which may be of any desired color, is laid on the proper metal in a wet granular state, and

it is rolled, troweled, or otherwise leveled, so as to produce an even compact surface. I then lay over this surface a stencihwhich may be of flexible metal, or of paper treated with oil, glycerine, or other suitable material or mixture, which will leave the paper soft and l allow it to be laid down close to the coating of the Wet enamel without becoming watersoaked. I then sift over the surface protected by this stencil a dry enamel-powder which is of a different shade or color from the body enamel already laid on the plate. I next remove the stencil, with whatever powder may be on the surface of it, and roll down on the body surface ofthe enamel the designs or configurations formed by the powder which has been sifted through the openings in the stencil. rIhe article, thus prepared, is then dried and put through an enameling-furnace, which will melt the enamel of different colors into each other and onto the surface of the iron, while leaving the design, letters, or figures perfectly clear and sharp.

The process of stenciling may be repeated with different or the same shades or colors, and different stencils or parts of stencils may be used to produce lines or shading to any desired extent.

The manner of stenciling above described may be reversedthat is to say, it may be carried out in the following manner:

(No model.)

The letters or designs may be cut out from metal or other material, or prepared separately and laid on the surface of wet enamel,

and then the enamel-powder of different colors may be sifted over the surface..

The pieces forming the gures, letters, or designs are then lifted off so as to leave these figures, letters, or designs of the color or shade of the original body ot' enamel first laid on the metal, and the article so prepared is then dried and passed through the enameling-furnace, as before.

I claim as my inventionl. The mode herein described of making enameled articles having' designs, letters, or figures thereon, said mode consisting in coating the article with `a body of wet enamel, applying dry enamel-powder to the surface while unfired, to form the designs, letters, or figures, and then firing the article, substantially as set forth.

2. The mode herein described of making enameled articles having designs, letters, or figures thereon, said mode consisting in coating the article with a body of. wet enamel, stenciling dry enamel-powder onto this surface while untired, and firing the article thus prepared, substantially as set forth.

3. The mode herein described of `making enameled articles with designs, letters, or ures thereon, said mode consisting in, iirst, coating the article with abody of wet enamel, evening and compacting the surface thereof, stenciling dry enamel-powder onto this wet surface, rolling the powder onto the body enamel, and, finally, drying and firing the artiele so prepared.

In testimony whereof I have signed my name to this specification in the presence of-two subscribing witnesses.
